CAP-SPIN DLE.

SPECIFICATION forming part of Letters Patent No. 619,064, dated February7, 1899. Application led February 10, 1898. Serial No. 669,754. (Nomodel.)

To all whom it may concern..-

Be it known that l, JOHN W. BAMFORD, of Pascoag, in the county ofProvidence and State of Rhode Island, have invented a new and usefulImprovement in Cap-Spindles; and I hereby declare that the following isa full, clear, and exact description of the same, reference being had tothe accompanying drawings, forming part of this speciiication.

This invention has reference to an improved lubricating device forspindles of cap-spinning machines; and it consists in the peculiar andnovel construction of an oiling-cup whereby oil is used over and overand filtered before each use or reuse, as will be more fully set forthhereinafter.

In spindles for cap-spinning machines the whirl and bobbin-support aremade t0 travel up and down on the dead-spindle. A portion of the spindlecovered with lubricating-oil is exposed to the atmosphere of thespinningroom, which is more or less, but always considerably, loadedwith iine dust and iloating fiber, which adhere to the oil-covered partof the spindle and mix with the lubricating-oil, into which they arecarried by the reciprocation of the bolster-rail and the oiling device.

The object of this invention is to provide for the taking up of thesurplus oil from the spindle and passing the oil through a strainingmaterial before it is again brought into contact with the spindle.

Figure l is a vertical sectional View of a cap-spindle provided with myimproved oiling device. Fig. 2 is a top view of the oiling device. Fig.3 is a bottom view of the lower oil cup or tray and holding device. Fig.liis a sectional view through the center of the two oil-cups and theholding device, showing the same secured together by a thimble. Fig. 5is a top view of the cover, andFig. 6 is a top view of the lower oil cupor tray.

Similar letters of reference indicate corresponding parts in all thefigures.

I have elected to illustrate my improved oiling device in connectionwith the rail as usually found in cap-spinning machines.

In the drawings, @indicates the stationary spindle of a cap-spinningmachine; b, the reciprocating rail by which the bobbin and its supportare moved up and down c, the bandpulley or whirl, and cl thebobbin-tube. The

whirl c is provided with the recess e, formed by the depending iange c',and the bearingblock n. This bearing-block is forced over the downwardextension of the tube d, so as to be driven by the whirl and may beformed of any suit-able material. The tray g is provided with a centralhole and the oil-holes h h. The cup z' has a central hole and theoilholes Z Z and annular sides, which extend upward into the recess e ofthe whirl.

The various parts of the oiling device are secured together in thefollowing order: The two pieces of felt o o are placed in the tray gover the holes h h. The cup e' is then placed with that portion of thebottom not having the holes in it so as to rest on the felt pieces o o.The thimble k is now passed through the central hole in the cup andthrough the central hole in the tray g. The holdingclamp r is thenplaced on the lower end of the thimble k with the two holes s s underthe holes h h, and then the lower end of the thimble k is spun over tohold all the parts in position. The upper flange of the thimble k formsan annular raised surface, on which the bearing-block 'n of the whirl issupported and revolved. m is a felt washer. This washer may be placed onthe flat top of the rail b, as shown in Fig. l, or a recess may be madein the rail to receive the felt washer. The holding clamp fr extendsoutward and is bent around the rail, as shown in Fig. l, to hold theoilingdevice against rotation.

I will now more fully describe the operation of the oiling device. Thelubricatingoil is placed into the tray g through the openings q q in thecover p, which covers the tray and prevents iiying pieces of lint orliber from lodging therein. The oil passes through the felt pieces o o,through holes h hin the tray g and through the holes s s in theholdingclamp r, into the felt washer m, and in passing through the feltpieces o 0 and the felt washer m deposits any impurities held insuspension in the oil. The felt of the washer m being in contact withthe spindle a supplies oil to the spindle. As the whirl c and tube (Zare moved up and down any surplus oil on the spindle between the uppersurface of the thimble k and the lower end of the bearing-block 'n isthrown outward by the rapidly-revolvin g edge f of the bearing-block IOOinto` the cup t' and passes through the holes Z Z into the tray g, fromwhich the oil filters through the pieces of felt 0 o and passes throughthe holes h h s s into the felt Washer m. The impurities in the oil areretained by the fibrous material of the felt pieces and felt Washer, andthe filtered oil is delivered to the spindle.

Economy in the use of oil, cleanliness yby preventing the throwing offof the oil, and perfect lubrication are secured by the use of thisdevice, which can be adapted to any form of cap-spinning machine.

Having thus described my invention, I claim as new and desire to secureby Letters Patent== l. In a lubricating device for cap-spinningmachines, the cup 'L' provided with holes, the tray g provided withholes, the felt pieces o, o,

placed under the solid portion'of .the cup t and over the holes h, h, inthe tray, and thethimble 'Zo for securing the cup and tray t0= getherand compressing the felt pieces o, o, between the same, substantially asherein shown and described.

2. In a cap-spinning machine, the combination with the spindle a, thetube OZ, the whirl c provided with the iange c and the bearing-block n,and the rail b, of the cup vl having holes Z, Z, in the bottom, the feltpieces o, o, the tray g provided with the holes h, h, the holding-cliprr, the thimble 7o for securing the cup, the tray, and the clip togetherand the upper flange of which forms the bearing for the Whirl, and thefelt Washer m, all substantially as herein shown and described.

In witness whereof I have hereunto set my hand.

JOHN W. BAMFORD.
